How will temperature affect the rate of photosynthesis? Write hypothesis here. (Be sure to relate how rare of photosynthesis wil

balandron [24]

Explanation:

The rate of photosynthesis increases withe increase in temperature. Photosynthesis like any other chemical reaction responds positively to an increase in temperature.

At high temperatures, enzymes that takes part in the photosynthesis can be destroyed. This is 20°C where enzymes are usually denatured.

Photosynthesis is the process where green plants manufacture their food using inorganic substances from the environment.
During photosynthesis, plants combines carbon dioxide with water and produces organic molecules and oxygen.
Like any other chemical reaction, the reaction will proceed faster with an increase in temperature.

Hypothesis: If temperature is increased then the rate of evolution of oxygen gas increases because the rate of chemical reactions increases with increase in temperature.

Since oxygen is a by product of photosynthesis, we can quantify its rate of production as temperature increases.

Hair Coloring Experiment

leva [86]

The independent variable (hair colorin) causes a response in the dependent one (colorin effectiveness). The constant variable can not change (curly or straight), the control variable is kept constant (time and environmental conditions). The experimental group receives the treatment (40 students).

------------------------------------------------

INDEPENDENT VARIABLE

Refers to all the variables in an experiment that provoke a response in another variable. The independent variable is modified to analyze its effects on another variable. The researcher changes on purpose the independent variable to observe the response of the dependent variable.

In the exposed example, the independent variable is the red hair coloring

- Red Hair Paint

- L’Oreal

DEPENDENT VARIABLE

Refers to the variable, which response depends on any change in the independent variable. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable.

In the exposed example, the dependent variable is the coloring effectiveness, seen through how well the coloring takes and lasts.

CONSTANTS

This variable does not change during the whole experiment and under any circumstance. It can not change.

In the exposed example, the constant variable is the type of hair, curly or straight.

CONTROL

Controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.

In the exposed example, the controlled variables are the exposure time to the colorings and environmental conditions, such as temperature, humidity, etc.

EXPERIMENTAL GROUP

The experimental group receives the treatment. The researcher apply different treatments to the experimental groups to observe how they affect the dependent variable. There can be several experimental groups.

In the exposed example, the general experimental group is the 40 students' hairs. Because coloring does not have the same effect on different hair colors, the experimental group includes,

- 10 blonds,

- 10 brunettes,

- 10 with black hair

- 10 with red hair

How does farming affect water, land, and air?

eimsori [14]

Excessive irrigation can affect water quality by causing erosion, transporting nutrients, pesticides, and heavy metals, or decreasing the amount of water that flows naturally in streams and rivers.
Soil erosion due to land clearance and grazing. contaminated soils due to pesticides or overuse of fertilizers.
Air emissions from livestock operations make up 14.5 percent of global greenhouse gas. Livestock farming emits several greenhouse gases that contribute to climate change, and may also be subject to the effects of climate change due to increased animal stress in dealing with rising temperatures.
